SOLD - FOR SALE: Sonic Frontier SFD-2 MKIII + PLATINUM PLUS UPGRADES + Assemblage D2D-1 Converter

Description

This is one of the best and most rare reference R2R DACs ever created for Redbook playback. Full differential, EIGHT BURR BROWN PCM1704 R2R multibit 24/96 chips (4 per leg), the best HCDC chips - PMD200 (a huge upgrade over the SDF-2 MKII that used the UA D2400A). Its analog stage uses the beautiful 6922 tubes.

This unit has a huge list of upgrades; the PCX Platinum Plus package is listed below. In my opinion, the only way to run such a high end DAC is to match it to the famous Assemblage D2D-1 Converter via the proprietary I2S-e umbilical (note, this is different than typical I2S cables). I'm including the D2D-1 with the sale, and will not separate them.

I bought this SDF-2 MKIII directly from Chris Johnson at Parts Express (the original founder of Sonic Frontiers) in June 2019. It was meticulously inspected by Chris, and given a perfect bill of health. The previous owner was a collector, so it has very little hours of use. This is an incredibly rare unit, with fewer than 100 MKIII units ever produced, and far fewer with the PLATINUM PLUS upgrade package that includes:
- V-Cap 10uf OIMP output coupling caps
- CARDAS XLR jacks
- Russian mil-spec 6H23P-eb ultra high-grade low noise 6922's (80's vintage)
- Teflon composite tube sockets
- DEXA discrete op amps (four duals for the I-V stage)
- TKD, Caddock, and Vishay signal resistors
- Upgraded NICHICON power supply caps
- CREE Scotty and SF4007 diodes
- ACME "Cryo silver" fuse
- EAR feet
- HiFi Tuning Supreme fuse
- Sound Coat chassis damping

Both units are in absolutely pristine collector's-level condition. My rating is an "8" due to age. I will ship in two separate boxes, which are the original boxes for each unit. Both boxes have molded foam, and the SFD-2 MKIII will be double boxed. The owners manuals, power cords, and I2S-e umbilical cord will be included.

Buyer pays shipping and PayPal fees.
